Abstract: The seedling breeding technology of Paris polyphylla Smith var. chinensis Franch. is the foundation of the development of the artificial planting industry. Through many years of experimental research on the seedling breeding technology of Paris polyphylla Smith var. chinensis Franch., the technical regulations for the seedling breeding of Paris polyphylla Smith var. chinensis Franch. were formulated. According to the requirements of "good agricultural practice for chinese crude drug", the research was carried out on the environmental requirements of production area for the seedling breeding of Paris polyphylla Smith var. chinensis Franch., the rearrangement of breeding ground, seed breeding, rhizome breeding, the management of breeding ground, disease and insect control, seedling excavation, seedling level, packaging, storage and transportation, in order to define the optimal methods and indicators of each key technology in the process of seedling breeding, and standardize the seedling breeding technology of Paris polyphylla Smith var. chinensis Franch., which could provide the technical support for the large-scale production of seedlings.
